I searched for shape features i.e. Image moments in opencv documentation. I searched for zernike moments. But there is only Hu moments is available in OpenCV documentation. Is there zernike moments available in opencv?

no such thing in opencv.

(also, are you sure, that shape analysis is the right application for zernike moments ?)

i am not sure @berak I found it used in one journal as shape feature. Then i searched for OpenCV function for it. But i cant find moment function other than moments( ) and HuMoments( ).

ah, good. i only knew them used for texture features, like convolving an img with zernike polynomials.

As berak said, there are no Zernike moments implemented yet. They are indeed very good shape descriptors, but can also be used as texture feature. Would be nice to have them in OpenCV ...
